Description

TECHNICAL FIELD

[0001] The present application relates to the field of building, in particular to a mounting structure of a rotating staircase. BACKGROUND

[0002] In the prior art, during the construction and installation of a rotating staircase, a plurality of tensioned steel pull rods are usually arranged between the main body foundation and the staircase ring beam for fixing the staircase box beam, and the tensioning force of each steel pull rod is usually 5KN. The current structure of the steel pull rod is that the lower end is fixed to the main body foundation and the upper end is fixed to the staircase ring beam. However, during the construction process, especially when the staircase is gradually constructed, the staircase deforms due to its own weight. The current steel pull rod cannot be adjusted, and only temporary supports are provided. Due to space reasons, the temporary support points cannot be arranged too much, so the deformation problem cannot be solved.

[0003] Therefore, those skilled in the art need to improve the existing mounting structure to overcome the above-mentioned defects. CONTENT OF THE UTILITY MODEL

[0006] The tension rod assembly comprises an upper tension rod fixedly connected with the upper end of the staircase ring beam and a lower tension rod fixedly connected with the lower end of the main body foundation. The lower end of the upper tension rod is rotatably provided with an adjusting frame. The inner side of the adjusting frame is provided with a plurality of clamping grooves, and the plurality of clamping grooves are uniformly distributed on the circumference with the rotating center of the adjusting frame as the center. A limiting frame is rotatably arranged on the lower tension rod, and a limiting column matched with the clamping groove is fixedly arranged on the limiting frame.

[0007] Further improvement is that the adjusting frame comprises a first bracket and a second bracket. A plurality of cross bars are fixedly connected between the first bracket and the second bracket. First ear rods and second ear rods are fixed on the cross bars.

[0008] Further improvement is that the limiting frame is in the shape of a fork, and the two ends of the limiting column are respectively fixedly connected with the limiting frame.

[0009] Further improvement is that the card slot is a semicircular slot, and the limiting column is a cylindrical column.

[0010] Further improvement is that the stair body comprises a stair box beam, a corrugated steel plate layer fixedly arranged on the surface of the stair box beam, and a building surface layer fixedly arranged on the surface of the corrugated steel plate layer.

[0011] Further improvement is that the stair box beam comprises a top sealing plate, side sealing plates fixedly arranged on both sides of the top sealing plate, a plurality of longitudinal partition plates vertically fixedly arranged below the top sealing plate, and bottom sealing plates fixedly arranged between the top sealing plate and the longitudinal partition plates or between adjacent longitudinal partition plates.

The limiting column 11 is erected on the first support and the second support, the overall structure has good stability, and the position of the limiting column 11 in the clamping groove 8 can be adjusted by the temporary support, thereby fine-tuning the length of the tension rod assembly, maintaining the tensioning force, avoiding serious deformation under gravity, and ensuring the stability of the overall building.

[0031] As shown in the figure, Figure 4 The limiting frame 10 is fork-shaped, and the two ends of the limiting column 11 are respectively fixedly connected with the limiting frame 10.
